Although we do not have an electric cooker/oven in the kitchen, that
may change with the nice new appliances now available.

The present cable is 6mm and access is open for all it's length except
in the walls where it's in conduit. I would like a ball-park figure
for the current carrying capacity of 6mm and 10mm cable with a view to
up rating as good housekeeping for the future, before access is
closed.

From the CU, 0.20m is in plaster, 8.00m is tacked to a joist in the
ceiling and the last 1.50m to the cooker box is in wall conduit.

Most grateful for any help
